Hi,
The patch at
http://comments.gmane.org/gmane.linux.kernel.initramfs/2244 takes
care of only the MAC conversion to lower case in the interface name.
But the same has to be taken care for BOOTIF also. This patch takes
care of changing the BOOTIF to lower case.
Note that sed has been used instead of tr, as dracut does not install
tr to the initramfs, atleast on RHEL 6.x.
Good to know, could you replace the existing interface MAC conversion
with sed too?
Attached a patch to do the same.
Sorry for sending the wrong patch yesterday. I am sending the correct
patch with both the patches.
Regards,
Seenu.
